In photography many times it has been seen that people get confused what is a "stop" and here today we will clear our topic of the stop. Stop is basically a part of exposure triangle only and in order to make it all simple in speaking photographers use the term stop.
We already discussed exposure triangle and in that, we also understood what is Aperture, Shutter Speed & ISO. We talked about what are these three and how these works in tandem and their working is calculated in stops. People get confused what does this term stop exactly mean & how it is being calculated, but what I personally feel and think is that we don't need to understand in depth how it is being calculated rather better to understand how can we bring it to our understanding and in our words to express the exposure setting or to convey the message in simple words like you want to tell someone to increase the brightness but by what amount ?
In that case, you need to say, increase brightness by 1 or 2 stops or whatever.
These are some jargon that you have to understand in a simple way, now everyone is free to learn what they want to. The Internet is a very vast place to search on any topic, even then I am writing about these things - the reason behind this is to let you know simply by sitting at one place and opening one blog so that you don't have to struggle to understand anything related to photography. Whatever I am sharing here is on the basis of my own study and experiments. Many times when I felt the need of understanding something related to photography, I even discussed with some of the photographers to understand those jargons and even small - small things about photography.
Now, again I come back to the topic that how stop is calculated, but we will do it in a simpler way so that we don't get confused and our concept is also clear. Here you will see that 10 clear stops are available and here what we will try to understand is how can we increase or decrease the stop. When we have to increase one stop in that case how we will calculate for that and not simply that we will first understand that how one stop then 2 and then 3 stops can be multiplied and we could get the desired result.
Below I have created this image somewhat awkward as I want to make it clear as much as possible and also wants to finish up with any confusion in mind related to exposure triangle.

As you can see below how the light meter looks in the viewfinder in DSLR cameras and if the green color moves towards right it means increased brightness and if the color moves to the left side it means darkness in the image, in order to maintain this, we need to calculate stops.

Suppose you have taken a shot with the setting of shutter speed 1/125, Aperture f/11 & ISO 100, you notice that the exposure has decreased by 2 stops now it means that you have to increase by 2 stops then only you will get the correct exposure. So, from the above table we see that we have 3 options either to increase the shutter, Aperture or ISO and for this we have to understand the need, if the situation demands the same shutter speed then we have to adjust either Aperture or the ISO. So, here we will increase one stop Aperture i.e. f/8.0 and one stop ISO - 200 and we will let the Shutter Speed same i.e. 1/125. When you increase the stop you double that in the case of Shutter Speed and ISO and move up as defined above, in the case of Aperture, but when we say decrease a stop we just half the number, in the case of Shutter Speed and ISO and move down in the case of Aperture as per the chart.
I hope now you are clear with the concept of increase or decrease in stops and you will not hate me for the way I have tried to explain this. Your comments are always welcome, to understand that how far I have been successful in explaining this topic.
